A study of the case of superlattices of Au nanoparticles passivated with thiol molecules is presented. The possibility of an orientation relationship among the nanoparticles is analyzed. It is concluded that for the case of Au the relationship does not exist. In‐situ experiments in the TEM showing loss of order and the melting conditions are reported and discussed. Different temperature ranges are clearly distinguished for the loss of the thiol–thiol bonds and for the Au nanoparticles–thiol bonds.
